Description

【0001】
【発明の属する技術分野】
本発明は、一般家庭に使用する自動炊飯器に関するものである。
【0002】
【従来の技術】
以下に従来の自動炊飯器の構成について説明する。図9において、自動炊飯器1は、少なくとも炊飯したい量の米を収納することができる貯米部2、米を計量する米計量部3、米計量部3から供給された米をとぐ米とぎ部4、米とぎ部4でとがれた米を炊飯する炊飯部5、米とぎ部4と炊飯部5を接続する米搬送部6を備えている。
【0003】
炊飯部5内には米と水を入れる鍋7が着脱自在に収納されている。鍋7の上面には鍋7全面を覆うように蓋体8が設置されている。この外蓋8は一方をヒンジ軸9により回動自在に軸支されており、外蓋8はヒンジ軸9を中心に、開放するのである。また鍋7に給水するための給水手段10が設置されており、水は給水手段10から給水経路11、水投入孔12へと順に水が鍋7に給水されていく。さらに、炊飯時に上方から米を加熱するための加熱手段である加熱板18と、加熱板18を発熱させるための蓋コイル19が設置されているのである。鍋7の底部を加熱する加熱手段として、底コイル20が鍋7底付近に配設されており、鍋7の側面を加熱するための側面コイル21も配設されているのである。
【0004】
また、鍋7に給米するための給米手段13が設置されており、米は給米手段13から米搬送部6、米投入孔15へと順に鍋7に給米される。ここで、水投入孔12、米投入孔15にはそれぞれ、水投入逆止弁16、米投入逆止弁17が設置されており、鍋7内に米や水が投入される時は水投入逆止弁16、米投入逆止弁17は水投入孔12と米投入孔15を開放して、水、米がそれぞれ投入される。逆に水、米を投入する時以外は、各々の逆止弁により各経路内への蒸気やおねばの浸入を防止しているのである。
【0005】
以上の自動炊飯器1を使用する動作を簡単に説明すると、まず鍋7をセットし、外蓋8を閉める。そして炊飯量を設定して炊飯スタートを行うとまず米計量部3が設定量の米を計測する。計測された米は米とぎ部4に送られて研米される。米とぎ部4にて研米された米は米搬送部6を通り、米投入孔15の米投入逆止弁17を押し下げ、炊飯部5内の鍋7内に投入される。
【0006】
所定量の米が投入されると次に自動給水が開始する。そして給水手段10により供給される水は水投入孔12の水投入逆止弁16を押し下げ鍋7内に投入される。
【0007】
所定量の米と水が鍋7に投入されると炊飯が始まる、というのが、炊飯動作の一般的なものである。
【0008】
【発明が解決しようとする課題】
しかしながら、前記の従来の技術の構成においては、逆止弁は自在に水投入孔および米投入孔の開閉を行うことはできず、給水時は水投入孔のみが開放し、給米時は米投入孔のみが開放する。また炊飯時、保温時等の給水、給米時以外は米投入孔、水投入孔は双方閉じられている状態にすることしかできなかった。この構成では、例えば送風機などにより米を鍋へ供給する場合、米搬送に必要な風圧は鍋内に充満し、蓋体に設けられた蒸気孔から空気が外部に放出することで鍋内部の圧力を減らすことになるが、蒸気孔はふきこぼれ、保温の関係であまり大きくすることができないため、鍋内の圧力は一時的にはかなりの圧力がかかった状態になってしまう。このために蓋体変形の促進や、蓋体のフック部の変形につながってしまうという問題点があった。
【0009】
本発明は、以上のような従来の炊飯器が有している課題を解決するものであり、米投入弁、水投入孔を自在に開閉することを目的とするものである。
【0010】
上記のような問題点では、水投入孔を開放することで、空気が水投入孔からも放出し、鍋内の圧力を下げることにより解消することが可能になるのである。加えて、空気が水経路内を通過することで、水経路内の乾燥をも可能になるのである。
【0011】
【課題を解決するための手段】
前記従来の課題を解決するために本発明の自動炊飯器は、水投入孔を開閉する水投入弁と、米投入孔を開閉する米投入弁と、前記米投入弁と前記水投入弁の少なくとも一方を自在に開閉する1つの駆動手段を備え、前記駆動手段の回転運動を伝達される駆動伝達手段と、前記駆動伝達手段回転運動を略鉛直運動に変換する水投入弁駆動手段と、前記駆動伝達手段回転運動を略鉛直運動に変換する米投入弁駆動手段とを備えたものである。
【0012】
これによって、駆動手段が、水投入弁、米投入弁を各々自在に開閉し、水投入弁、米投入弁の開閉状態を炊飯および保温における最適条件に設定することができるものである。さらに、駆動伝達手段により米投入弁および、水投入弁の開閉が自在に操作できる自動炊飯器を提供することができる。
【0013】
【発明の実施の形態】
請求項1記載の発明は、米を炊飯する炊飯部と、前記炊飯部内に着脱自在に収納される鍋と、前記鍋の上面開口部を覆う蓋体と、前記炊飯部に給水する給水部と、前記炊飯部に給米する給米部と、前記蓋体に有した水投入孔と米投入孔と、前記水投入孔を開閉する水投入弁と、前記米投入孔を開閉する米投入孔と、前記米投入弁と前記水投入弁の少なくとも一方を自在に開閉する1つの駆動手段と、前記炊飯部、前記給水部、前記給米部および前記駆動手段を制御する制御部とを備えたことにより、給米工程で水投入弁を開放し、負荷のかからない給米が可能になるのである。
【0014】
また、給水工程においては、例えば給水時に米投入孔を開放できる構成にした場合、水投入時の鍋内の空気が米投入孔から外部に放出できるために、蒸気孔からの放出が必要なくなる。このことで、蒸気孔と水投入孔を共用にすることができ、蓋体のコンパクト化が実現するのである。
【0015】
加えて保温工程に米投入孔を開放し、風を送り、余分な水分を飛ばし、保温性能の向上をも可能になるのである。
【0016】
以上のように米投入孔および、水投入孔を自在に開閉することで、給米および給水性能の向上のみならず、保温性能の向上、製品のコンパクト化を実現できる自動炊飯器を提供することができる。
【0017】
さらに、駆動手段の回転運動を伝達される駆動伝達手段と、前記駆動伝達手段回転運動を略鉛直運動に変換する水投入弁駆動手段と、前記駆動伝達手段回転運動を略鉛直運動に変換する米投入弁駆動手段とを備えたことにより、駆動伝達手段により米投入弁および、水投入弁の開閉が自在に操作できる自動炊飯器を提供することができる。
【0018】
請求項記載の発明は、特に請求項1に記載の発明において、水投入弁の開閉を検知する水投入弁開閉検知手段と、米投入弁の開閉を検知する米投入弁開閉検知手段とを有することにより、検知手段が各々の投入弁の開閉を認識するため、駆動手段が1個の場合においても各々の投入弁の開閉状態を認識する自動炊飯器を提供することできるのである。
【0019】
請求項記載の発明は、特に請求項1〜のいずれか1項に記載の発明において、水投入時は水投入弁を開放し、米投入弁を閉じたことにより、水投入時の鍋や水同士の跳ね返りによる水しぶきが給米経路に浸入することを防止し、給米機能が向上した自動炊飯器を提供することができる。
【0020】
請求項記載の発明は、特に請求項記載の発明において、制御部が、水投入弁駆動手段が開放するときに米投入弁駆動手段が開放しないように駆動伝達手段の回転位置を静止させることにより、水投入時の鍋や水同士の跳ね返りによる水しぶきが給米経路に浸入することを防止し、給米機能が向上した自動炊飯器を提供することができる。
【0021】
請求項記載の発明は、特に請求項1〜のいずれか1項に記載の発明において、水投入弁は水の給水停止時より遅延して閉じることにより、水投入完了直後の給水経路内に存在する残水を鍋内に投入が完了してから水投入弁を閉めることができ、給水時以外は給水経路の残水を無くすことができる自動炊飯器を提供することができる。
【0022】
請求項記載の発明は、特に請求項1〜のいずれか1項に記載の発明において、米投入時は米投入弁を開放し、水投入弁は閉じたことにより、米投入時における、砕米や米糠が給水経路内に侵入することを防止した自動炊飯器を提供することができる。
【0023】
請求項記載の発明は、特に請求項に記載の発明において、制御部が、米投入弁駆動手段が開放するときに水投入弁駆動手段が開放しないように駆動伝達手段の回転位置を静止させることにより、米投入時における、砕米や米糠が給水経路内に侵入することを防止した自動炊飯器を提供することができる。
【0024】
請求項記載の発明は、特に請求項1〜のいずれか1項に記載の発明において、炊飯時、保温時、給米時は、水投入弁を閉じたということは、炊飯時、保温時、給米時以外では水投入弁が開放することであり、これらのことにより水投入経路の乾燥を保持することができる自動炊飯器を提供することができる。
【0025】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【0026】
(実施例1)
図1〜3を参照し、実施例1を説明する。自動炊飯器30は、少なくとも炊飯したい量の米を収納することができる貯米部31、米を計量する米計量部32、米計量部32から供給された米をとぐ米とぎ部33、米とぎ部33でとがれた米を炊飯する炊飯部34、米とぎ部33と炊飯部34を接続する米搬送部35を備えている。水タンク36は水タンク収納部37に着脱自在に収納されて、水タンク36の底にはインペラー38が設けられ、インペラー38の下方部にはインペラー38を回転させるモーター39が配設されている。
【0027】
40は制御部で、米計量部32、米とぎ部33、米搬送部35、給水部であるインペラー38、炊飯部34を制御する。
【0028】
米とぎ部33は、米計量部32で計量された米を収納する米収納容器41、米収納容器41内で回転自在に配設された回転羽根42、回転羽根42を駆動する米とぎ駆動手段43を備えている。
【0029】
米搬送部35は、米搬送ファン(図示しない)が生み出す空気流により米を炊飯部34へ搬送する。搬送された米を鍋45に投入するための米投入孔65と米投入孔65を開閉する米投入弁64が設けられている。
【0030】
炊飯部34の詳細を説明すると炊飯部34は米を調理する着脱自在の鍋45、鍋45上方を覆うように設置されている蓋体46、鍋45を設置する本体47で構成されている。蓋体46は一方をヒンジ軸48に軸支されており、蓋体46開放時はヒンジ軸48を中心にして回動しながら蓋体46は開放する。また蓋体46には炊飯中の蒸気を炊飯部34外に排出する蒸気排出部49を設けていると共に、ご飯を上方から加熱するための加熱板50が設定されており、加熱板50を加熱するための加熱手段として蓋コイル51が加熱板50近傍に設置されている。鍋45を加熱する加熱手段としては鍋45底部を加熱する底コイル52、側面を加熱する側面コイル53が鍋45の外面形状に沿うように設定されており、炊飯は底コイル52、側面コイル53、蓋コイル51の全ての加熱手段を使用して炊飯を行うのである。また鍋45の底面中央には底センサー54が鍋45に圧接される状態で設置されており、炊飯中の鍋45の温度を常に測定しているのである。
【0031】
この炊飯部34には給水経路56、水投入弁57、水投入孔58が設けられている。また水投入孔58は加熱板50に設けられており、この水投入孔58の開閉を行うための水投入弁57が設置されているのである。水投入孔58の周囲には水投入パッキン60が設置されており、水投入孔58と水投入弁57とのシールを行っている。この水投入弁57が水投入孔58を開閉する構成としては、水投入弁57が上下方向に動作し、水投入パッキン60と水投入弁57の間に隙間ができることにより開閉しているのである。水投入弁57を上下方向に動作させる構成としては、駆動手段である駆動モーター61の回転運動を上下方向の運動に変化させるわけであるが、これらはまず、駆動モーター61の回転を駆動伝達手段である水投入弁駆動歯車62に伝える。この水投入駆動伝達歯車62は側面に凸部(網掛け部)を設け、この凸部と底面部を傾斜面で繋いた形状をしているのである。この水投入弁駆動歯車62は軸が鉛直方向になるように設置されており水平方向に回転する。また中央部分が軸支され、軸支された位置を中心に鉛直方向に運動する弁駆動手段である水投入弁駆動レバー63が水投入弁駆動歯車62付近に設置されており、水投入弁駆動レバー63の一方が水投入弁駆動歯車62の側面に形成された凸部により略鉛直方向に動作し、水平方向の回転運動を鉛直方向の回転運動に変化させるのである。そして、水投入弁駆動レバー63のもう一方側が水投入弁57を動作させることにより、付勢バネ66により常に上方に付勢されている水投入弁57が上下運動をするのである。
【0032】
米投入弁64も水投入弁57と同様の機構により動作し、米投入孔65を開閉しているので、詳細な説明は省略する。
【0033】
上記構成において、動作を説明する。使用者が米を貯米部31内に投入し、炊飯したい米の量を入力した後、運転開始ボタン(図示しない)を押すと、自動炊飯器30の運転が開始する。
【0034】
運転が開始されると、制御部40は、使用者が設定した炊飯量に最適な量の水を、給水経路56を介して炊飯部34の鍋45へ供給する。
【0035】
次に、制御部40は米計量部32を動作させる。そして、米計量部32は、所定量の米を米収納容器41へ供給する。
【0036】
所定量の米が米収納容器41に供給されると、制御部40は米とぎ工程プログラムに従って米とぎ駆動手段43を動作させる。米研ぎ駆動手段43が動作することにより回転羽根42が回転し、米収納容器41内に収納された米をとぐ米とぎ工程が行われる。
【0037】
米とぎ工程が終了すると、制御部40は米搬送工程プログラムに従って米搬送ファンおよび米投入弁64を動作させる。そして、米とぎ部33でとがれた米を、米搬送部35を介して炊飯部34の鍋45へ供給する。
【0038】
このようにして、所定量の水と米が鍋45へ供給されると、制御部40は米に水を吸収させる浸漬工程プログラムおよび炊飯工程プログラムに従って炊飯部34を動作させる。炊飯部34が動作することにより、使用者が炊飯したい量の米が炊飯されることになる。所定量の米が炊飯されると、制御部40は、ご飯を保温する保温工程に入る。こうして、ご飯が炊きあがる、というような自動炊飯器が可能になるのである。
【0039】
以上のように水投入弁57、米投入弁64を駆動手段により動作させることにより、水投入孔58、米投入孔65の開閉が自在にできるようになり、水投入孔58、米投入孔65をどちらも同時に開放したり、閉じたりすることができる。あるいは、水投入孔58のみを開放し、米投入孔65を閉じたり、米投入孔65のみを開放し、水投入孔58を閉じたりすることができる。以上のような開閉状態が炊飯工程のどの工程においても、各々の投入孔の開閉が自在にできるようになるのである。これらの各々の開閉状態での効果は後に詳細を説明する。
【0040】
また、本実施例においては弁駆動手段の動作をモーターの回転を歯車で上下方向の運動に変換して動作させていたが、駆動方法については、モーター方式だけに限定するものではなく、投入孔を開閉する駆動手段を有していればよい。
【0041】
また、本実施例は水投入弁57、米投入弁64にそれぞれ駆動手段を設けて説明したが、水投入弁57および米投入弁64の駆動手段は図4に示すように、水駆動伝達歯車62と米駆動伝達歯車68を設け、水投入用レバー63、米投入用レバー67のそれぞれの動作ができるようしている。このように、一つの駆動手段で水投入弁駆動レバー63と米投入弁駆動レバー67の両方を動作させ、水投入孔58と米投入孔65の開閉を行ってもよい。
【0042】
また、給米部は米とぎ部33を持たず、貯米部31と米計量部32、米搬送部35のみを備えた無洗米対応の構成のものであってもよい。
【0043】
また、自動炊飯器30の動作の説明では、炊飯部34に水を供給してから米を供給するようにしたが、米を供給してから水を供給してもよいし、水と米を同時にまたは交互に供給してもよい。
【0044】
(実施例2)
図5、6を参照し実施例2を説明する。自動炊飯器の基本構成としては、前述の構成と同様のため説明は省略する。炊飯部70には給水機構と給米機構が設けられており、加熱板71には、水投入孔72、米投入孔73が設けられており、また、この水投入孔72、米投入孔73の開閉を行うための水投入弁74、米投入弁75が設置されているのである。これらの水投入弁74、米投入弁75の動作は水投入弁駆動レバー76、米投入弁駆動レバー77によって動作しているが、この各々のレバーは駆動伝達歯車78の側面に形成された凸面(網掛け部)により上下運度を行っている。詳しく説明すると、駆動伝達歯車78側面を中心側78aと外周側78bに凸部を設ける。そして水投入弁駆動レバー76の一端を外周側78bに、米投入弁駆動レバー77の一端を中心側78aに当接するように設置する。そして駆動伝達歯車78が回転すると、側面の凸部が各投入レバーの一端にきた時に、それぞれのレバーが押し上げられ、もう一端が各投入弁を押し下げ、投入孔が開放するのである。ここで、駆動伝達歯車78の側面の中心側78aと外周側78bの凸部を検知する検知手段である水投入弁開閉検知マイクロスイッチ79と米投入開閉弁検知マイクロスイッチ80を設置する。以上のような構成にすることにより、水投入孔72、米投入孔73の開閉が検知でき、開閉制御が可能になるのである。つまり各マイクロスイッチが駆動伝達歯車78の凸部を検知するとON、凸部以外はOFFになるように設置することで、水投入孔72が開放、米投入孔73が閉じた場合は水投入弁開閉検知マイクロスイッチ79がON、米投入開閉検知マイクロスイッチ80はOFFする。また水投入孔72、米投入孔73が双方開放するときは、水投入弁開閉検知マイクロスイッチ79、米投入弁開閉検知マイクロスイッチ80が両方ともOFFする。と言うように水投入孔72、米投入孔73の開閉がどのような組み合わせになろうとも、各々のマイクロスイッチのON、OFFの組み合わせにより、検知が可能になり、各投入孔の開閉は自在の操作できるようになるのである。
【0045】
また、本実施例はマイクロスイッチにて投入孔の開閉を検知する構成を説明したが、マイクロスイッチに限定するのではなく、リードスイッチであろうが、フォトセンサーであろうが検知手段は限定しない。
【0046】
また、本実施例は各々の投入弁の開閉手段を一つの駆動手段で行うことができる構成を説明したが、駆動手段の数量、方式は問わない。
【0047】
(実施例3)
自動炊飯器の基本構成、水投入孔90の開閉手段、米投入孔91の開閉手段としては、前述の構成と同様のため説明は省略する。図7、8に示すように駆動伝達歯車92の側面を中心側92aと外周側92bに分け、図7、8のように網掛け部を凸形状にし、斜線部は傾斜面として底面部と繋ぐ形状にし、中心側92aと外周側92bとで凸になる部分を90°ずらす形状とする。そして外周側92bに米投入弁駆動レバー93、中心側92aに水投入弁駆動レバー94を駆動伝達歯車92の中心に対向するように当接させる。また米投入孔開閉検知マイクロスイッチ95を米投入弁駆動レバーの当接位置よりも45°反時計回りに移動させた位置に設置し、水投入孔開閉検知マイクロスイッチ96を水投入弁駆動レバー94の当接位置よりも45°時計回りに移動させた位置に設置する。
【0048】
以上のような構成にすることで、給水時は図7のように駆動伝達歯車92が回転し、水投入弁駆動レバー94の当接位置に凸部がくると、水投入孔90は開放状態になる。また、この時米投入弁駆動レバー95は凸部以外の位置で当接しているため、米投入孔91は閉じた状態になる。これらの位置を検知するために開閉検知マイクロスイッチを設けているが、この時水投入孔弁開閉検知マイクロスイッチ96はON、米投入弁開閉検知マイクロスイッチ95はOFF状態になっており、各投入孔の開閉の検知は確実にできているのである。
【0049】
これらのように、給水時に水投入孔90が開放し、米投入孔91が閉じる状態にできることで、給水時に鍋(図示しない)への飛び散りや水同士では跳ね返りにより発生する水分を米投入孔91から内部に浸入することを防ぐことができるのである。
また、米投入時にはさらに駆動伝達歯車92が回転して、米投入用レバー97の当接位置に凸形状がきた場合米投入孔91は開放状態になり、逆に水投入弁駆動レバー94は凸部以外で当接しているため、水投入孔90は閉じた状態になる。これらの位置を検知については米投入開閉検知マイクロスイッチ95がONになり、水投入孔開閉検知マイクロスイッチ96はOFFになっている為、この位置での開放状態は検知してこの状態になっているのである。
【0050】
以上のような構成にすることで、米投入時は米投入孔91を開放し、水投入孔90を閉じることにより、米投入時に発生する米糠や、砕米が水投入孔90から内部に侵入することを防止し、給水経路98内の清潔性を保つことができるのである。
【0051】
また、炊飯時、保温時、給水時は水投入孔90を閉じるとしたとすると、言い換えると炊飯時、保温時、給水時以外の工程、例えば、何もしていない待機状態などにおいて水投入孔90は開放しているということである。このように炊飯、保温、給水以外の待機時などの工程で水投入孔90が開放しているということは、給水経路(図示しない)の水分を自然乾燥することが出来、給水経路内には常に乾燥しているため、菌などの発生を防ぐことが出来、清潔で安全性の高い炊飯器を提供することができるのである。
【0052】
また、給水工程において、給水が開始し、所定水量を検知し、給水を停止するが、停止した直後に水投入孔90を閉じるのではなく、一定時間後に水投入孔90を閉じるようにしている。このような動作にすることにより、給水を停止した直後には給水経路内には水が存在しているが、これらの水が鍋(図示しない)内に投入完了した後に水投入孔90を閉じるようにしているのである。このように給水経路90内の水を完全に鍋内に投入することで、いつも一定量の水が鍋内に投入されることになり、給水量の繰り返しバラツキの誤差が減少し、給水量精度の向上につながる。更に、給水経路98内に水分を残さないようにできるため、給水経路内の菌の発生をも抑えることができるのである。
【0053】
【発明の効果】
以上のように、請求項1〜に記載の発明によれば、給水、給米、炊飯、保温など各工程において米投入弁、水投入弁を自在に開閉することで、各工程における最適な投入弁の開閉状態が可能になり、信頼性、安全性の高い品質の安定した炊飯器を提供することができるのである。

[0044]
(Example 2)
A second embodiment will be described with reference to FIGS. Since the basic configuration of the automatic rice cooker is the same as that described above, the description thereof is omitted. The rice cooking unit 70 is provided with a water supply mechanism and a rice supply mechanism, and the heating plate 71 is provided with a water introduction hole 72 and a rice introduction hole 73, and the water introduction hole 72 and the rice introduction hole 73 are provided. A water charging valve 74 and a rice charging valve 75 for opening and closing the rice are installed. The water charging valve 74 and the rice charging valve 75 are operated by a water charging valve driving lever 76 and a rice charging valve driving lever 77. These levers are convex surfaces formed on the side surfaces of the drive transmission gear 78. The up and down luck is done by (shaded part). More specifically, convex portions are provided on the side of the drive transmission gear 78 on the center side 78a and the outer peripheral side 78b. Then, one end of the water injection valve drive lever 76 is installed in contact with the outer peripheral side 78b, and one end of the rice injection valve drive lever 77 is installed in contact with the center side 78a. When the drive transmission gear 78 rotates, when the convex portion on the side surface comes to one end of each closing lever, each lever is pushed up, the other end pushes down each closing valve, and the closing hole is opened. Here, a water introduction valve opening / closing detection microswitch 79 and a rice introduction opening / closing valve detection microswitch 80 which are detection means for detecting the convex portions on the center side 78a and the outer periphery side 78b of the side surface of the drive transmission gear 78 are installed. With the above configuration, the opening / closing of the water introduction hole 72 and the rice introduction hole 73 can be detected, and the opening / closing control can be performed. In other words, when each micro switch detects the convex portion of the drive transmission gear 78, it is set to be ON, and other than the convex portion is turned OFF, so that when the water introduction hole 72 is opened and the rice introduction hole 73 is closed, the water introduction valve The open / close detection microswitch 79 is turned on, and the rice insertion open / close detection microswitch 80 is turned off. When both the water introduction hole 72 and the rice introduction hole 73 are opened, both the water introduction valve opening / closing detection microswitch 79 and the rice introduction valve opening / closing detection microswitch 80 are turned OFF. As described above, regardless of the combination of opening and closing of the water charging hole 72 and the rice charging hole 73, detection can be made by the combination of ON and OFF of each micro switch, and the opening and closing of each charging hole can be freely performed. It will be possible to operate.
[0045]
Moreover, although the present Example demonstrated the structure which detects opening / closing of an insertion hole with a micro switch, it is not limited to a micro switch, it is a reed switch, it is a photo sensor, but a detection means is not limited. .
[0046]
Further, although the present embodiment has described the configuration in which each closing valve can be opened and closed by one driving means, the number and method of the driving means are not limited.
[0047]
(Example 3)
Since the basic configuration of the automatic rice cooker, the opening / closing means of the water charging hole 90, and the opening / closing means of the rice charging hole 91 are the same as those described above, description thereof will be omitted. As shown in FIGS. 7 and 8, the side surface of the drive transmission gear 92 is divided into a central side 92a and an outer peripheral side 92b, and the shaded portion is convex as shown in FIGS. The shape is formed so that the convex portions on the center side 92a and the outer peripheral side 92b are shifted by 90 °. Then, the rice injection valve drive lever 93 is brought into contact with the outer peripheral side 92b, and the water injection valve drive lever 94 is brought into contact with the center side 92a so as to face the center of the drive transmission gear 92. Further, the rice introduction hole opening / closing detection micro switch 95 is installed at a position 45 ° counterclockwise from the contact position of the rice introduction valve driving lever, and the water introduction hole opening / closing detection micro switch 96 is installed in the water introduction valve driving lever 94. It is installed at a position moved 45 ° clockwise from the contact position.
[0048]
With the above configuration, when water is supplied, when the drive transmission gear 92 rotates as shown in FIG. 7 and a convex portion comes in contact with the water supply valve drive lever 94, the water supply hole 90 is opened. become. At this time, since the rice insertion valve drive lever 95 is in contact with a position other than the convex portion, the rice insertion hole 91 is closed. An open / close detection microswitch is provided to detect these positions. At this time, the water input hole valve open / close detection microswitch 96 is ON, and the rice input valve open / close detection microswitch 95 is OFF. The detection of opening and closing of the hole is made reliably.
[0049]
As described above, when the water supply hole 90 is opened at the time of water supply and the rice input hole 91 can be closed, moisture generated by splashing into a pan (not shown) or rebounding between water during water supply can be removed. It is possible to prevent intrusion from the inside.
Further, when the rice is thrown in, the drive transmission gear 92 further rotates, and when the convex shape comes into contact with the rice throwing lever 97, the rice throwing hole 91 is opened, and conversely, the water throwing valve driving lever 94 is convex. Since the contact is made at a portion other than the portion, the water injection hole 90 is closed. Regarding the detection of these positions, the rice input opening / closing detection microswitch 95 is ON and the water injection hole opening / closing detection microswitch 96 is OFF, so the open state at this position is detected and becomes this state. It is.
[0050]
With the configuration as described above, when rice is introduced, the rice introduction hole 91 is opened and the water introduction hole 90 is closed, so that rice bran and broken rice generated at the time of rice introduction enter the interior from the water introduction hole 90. This can be prevented and the cleanliness in the water supply path 98 can be maintained.
[0051]
Further, if the water injection hole 90 is closed during cooking, heat retention, and water supply, in other words, the water injection hole 90 in a process other than rice cooking, heat retention, and water supply, for example, in a standby state where nothing is done. Is open. In this way, the fact that the water inlet hole 90 is open in a process other than rice cooking, heat insulation, and standby time other than water supply can naturally dry the water in the water supply path (not shown), Since it is always dry, it is possible to prevent the generation of bacteria and the like, and to provide a clean and safe rice cooker.
[0052]
Further, in the water supply process, water supply is started, a predetermined amount of water is detected, and water supply is stopped, but the water supply hole 90 is not closed immediately after the stop, but is closed after a certain time. . By performing such an operation, water is present in the water supply path immediately after the water supply is stopped, but the water supply hole 90 is closed after the water has been supplied into the pot (not shown). It is doing so. In this way, when the water in the water supply path 90 is completely poured into the pan, a constant amount of water is always poured into the pan, and the error of repeated variations in the amount of water supply is reduced, and the accuracy of the water supply amount is reduced. Leads to improvement. Furthermore, since it is possible to prevent moisture from remaining in the water supply path 98, generation of bacteria in the water supply path can be suppressed.
[0053]
